Hi all, I have a 2010 frontier and have an exhaust question. I'm looking to replace my muffler with a 5" MagnaFlow Round body, one that I have off of another car I owned. The diameter is 2.25". I'm wondering if adding this will decrease low end torque to the point where I would notice it. I'm really not looking to gain a whole lot, I just have this muffler and want a little better sound out of the truck, and possibly a little better fuel milage. What do you think?

I'm pretty sure the stock Y pipe is 2.25" - it may help with some backpressure...increasing...low end torque.

Either way, 1/4" isn't going to make that much of a difference. 3-5WHP. Butt dyno doesn't even pick that up.

Like I said, i'm not really looking for increased whp. I'm more looking for sound without a LOSS
